The exact causes of chronic kidney failure are unknown, although the debilitating loss of healthy kidney tissue may be a natural endpoint for several readily recognizable conditions, including advanced dental disease and a variety of kidney infections, inflammations and obstructions.
Sodium chloride was needed to ensure the proteins in the cell aren't separated from the rest of the solution with the DNA. Okay, the person above does not understand Chemistry nor the English language. The sodium chloride, NaCl, is a polar molecule, which would help separate an emulsion of two layers in an acid-base extraction. Since NaCl is polar, it would be easily dissolved into the solution and tie up the different layer molecules.
Ethanol precipitation is a commonly used technique for concentrating and de-salting nucleic acids (DNA or RNA) preparations in aqueous solution. The basic procedure is that salt and ethanol are added to the aqueous solution, which forces the precipitation of nucleic acid nucleic acids out of solution.he wash step removes the relatively small amount of salt that pellets with the DNA. This small amount of salt can dissolve in the 70% ethanol/30% water mix â mainly in the water part as the salt is far more soluble in water than in ethanol.
